An RMA number is a Return Merchandise Authorization. Using this number is an easy way to identify a return. At Returnly, we print that RMA right on the shipping label, so you don't have to open the box to know what it contains. This also saves your shoppers time, so they don't have to print both a shipping label and packing slip.
